So i have GH3 and i was thinking of just getting the RB disc when it comes out... Right now Gamestop has the Nyko Guitar on sale... i was thinking of getting that since i want another guitar for GH and i might be able to use it for RB...I would like to know if you guys think its a good deal... I heard about the Nyko Guitar working for both GH3 and RB on the PS3... Or does anyone know if the Nyko one will work with RB?
